[SOLVED] Can not get full speed out of Intel Wireless 9462

baens · 2020-11-17 12:07:44

Hello!

So I've tried and tried to get my full internet speed out of my Intel NUC running Arch and for the love of it, I just can't. I would expect to get around 100mb/s but current sitting around 20mb/s.

Here is my current hardware and configurations:

>cat /etc/modprobe.d/wireless-reg.conf
options cfg80211 ieee80211_regdom="US"

Here is what I've tried:

I've tried to install CRDA and setting the WIRELESS_REGDOM=US in /etc/conf.d/wireless-regdom, but the device's regulatory domain doesn't change. The global one does though.
I've added and removed things in /etc/modprobe.d, yet nothing seems to change anything.
I've removed CRDA and modprobe entires and just let it be the default, and that doesn't change anything.

Any advice or things I should try?

This seems similar https://bbs.archlinux.org/viewtopic.php?id=245690

Sadly, setting the parameter did nothing

Saw that, maybe I’ll downgrade to LTS and see if that fixes things. Thanks!

Downloading to the LTS version fixed my issue.

I tried rotating the different firmwares and everything and nothing seems to fix the issue with the latest kernel. Guess I'll try to reach out to the driver team and see if I can get any other answers.

I did notice that on the Intel firmware page, it is listing a different firmware version then what the driver wants to load.
